Welcome to the Bienne and Morez gorges, in a part of Jura that remains a well-kept secret. This is a great place to get together with friends for little adventures and big reunions during a weekend on the hiking trails and dizzying via ferrata courses. Not forgetting the small yet wild Bellefontaine lake. Then there's the museum devoted to what appear at first to be somewhat ordinary objects - spectacles - but which are in fact quite fascinating and, more importantly, made in Jura! And for other places to visit, you can count on our recommendations!

Day 1 - Morning

The viaducts hiking trail

Tackle famous viaducts on a hiking itinerary that starts at Morez tourist office. These architectural works of art, which are listed historical monuments, never fail to impress. Throughout your hike you'll have the pleasure of contemplating them from every angle:

- First of all, from underneath, to appreciate the colossal scale of the tasks carried out in the early 20th century.

- Then, you'll explore the Bienne valley to observe from high above how the structure is embedded in the mountains.

- Lastly, you'll board a regional express train on the Hirondelles line, the railway that crosses the viaducts on its path between Morbier and Morez, offering lots more to see along the way!

Practical info: challenging 16-km loop with a 600-metre elevation range. You can make your walk shorter by taking the train between the stations of Morez and Morbier.

Morez eyeglasses: not just an object, French expertise at its best!
Musée de la lunette / BFC Tourisme

The purpose behind the museum's creation? To retrace the town's entire history, from its origins to its industrial growth and its decline with the arrival of Chinese glasses on the market. The museum also highlights the modern-day spectacle makers who perpetuate this expertise that remains well-established in the Bienne valley.

In 1996, the town of Morez obtained the 'Ville et Métiers d’Art' seal of approval in recognition of its eyewear and enamel expertise, making Morez the very first town in Jura to receive this certification label. A just reward for a traditional savoir-faire found nowhere else!

The little extra that makes all the difference

Fondue in the great outdoors

For your lunch break, why not enjoy a meal of fondue in the great outdoors? Pack a fondue pot in your rucksack along with fondue forks and comté cheese from the Fromagerie de Morbier and off you go! If you don't have a fondue set, La Besace à Fondue has complete kits available for rent!

Tips for mindful behaviour in natural habitats: for your fondue you may be planning to use a gas camping stove... Please be aware that 9 out of 10 forest fires are caused by humans. If you need to use a camping stove, place it on stable ground away from vegetation. There may be a temporary ban on lighting fires, so check before you leave for any prefectoral or local bylaws.
